Brainwaves · Light + Sound

Notice your state. Explore your brainwaves.

Sensory entrainment is a broad term for the nervous system’s response to repeated rhythmic stimulation. In research settings, rhythmic light or sound can produce measurable activity linked to the timing of the stimulus. The strength and meaning of that response vary across people and conditions.

Ayurveda helps Jo or a certified NeuroVeda practitioner ask about the person: patterns, rhythms, history, preferences, and what is happening now. Neuroscience helps describe parts of sensory response and attention. Ayurveda does not determine a brainwave target, and neuroscience does not prove a dosha. The two lenses meet in the way an experience is prepared, paced, and reflected upon.

DELTA
0.5-4 Hz
slower activity
THETA
4-8 Hz
low-frequency activity
ALPHA
8-12 Hz
often studied with rest and attention
BETA
13-30 Hz
commonly present in alert waking activity
GAMMA
30+ Hz
high-frequency activity under active study

What state is your mind in
right now?

Your brain produces different rhythms depending on how you feel. Tap the one that fits and we'll take your word for it, then show you which rhythms it lines up with, and what you might listen to.

Brainwave States

Each of those states sits alongside a different frequency band. Listen, feel, and explore.

Frequency Spectrum

Each bar shows a brainwave band's frequency range Frequency = how many times per second the wave repeats. Measured in Hz (Hertz). Lower = slower brain activity. . Hover for details.

Breathe
Enable breathwork and play a band to begin

Audio frequencies are transposed from each band's geometric mean The "middle" of a frequency range on a logarithmic scale. For a range of 4–7 Hz, the geometric mean is about 5.3 Hz. ×64 (six octaves up) into the audible range. Binaural mode Plays two tones offset by the EEG frequency — one in each ear. Your brain perceives the difference as a gentle pulse matching the brainwave rhythm. produces a perceived beat at the brainwave frequency itself. Flicker animations pulse at the native EEG frequency and respect your system's reduced-motion preference. All audio and flicker stops automatically when this page is backgrounded.
